Procedure

To a solution of 3-chloro-5-fluoro-4-(quinolin-3-yloxy)phenylamine (186.2) (0.420 g) in pyridine(2.2 ml), was added 2,4-dichloro-5-methylbenzenesulfonylchloride 0.360 g. The mixture was stirred at room for 1 hr. The reaction mixture was purified directly by column chromatography (silicagel, AcOEt:Hexane=1:3). The product was triturated by hexane to give title compound (0.522 g). (73%) as a solid.
